provided with theusual :finger key 7' andA with a hook 8 which bears upon a transverse universal bar 9, that has a rearwardly eX- teiiding arm at each end which is pivoted to the frame of the machine at 10.

Pivoted to the universal bar 9 at 11 is a link 12 preferably made of two parts, which may be adjustably united by screw threaded connections 13. T he upper end of this link 12 is provided with an eye 14 that engagesv a notched portion 15 of an arm 16, which is preferably in the' form of a screw, that extends through a threaded hole in adepending stud 17 of the dog rocker, whereby the said arm may be adjusted to bring the inner end thereof closer to or to move vit farther from the pivotal center of the rocker, in order to vary or regulate the throw im parted to the rocker and the feed dogs carried thereby. The adjustment 13 enables the link 12 to be lengtliened or 'shortened in accordance with the 'adjustment of the arm 1G.

- The feed dogs 18 18 and their rocker 19 after actuation are returned to normal position by a spring 20, which is suitably connected at one end to an arm 20* on the rocker (see Fig. 1) and at its other end to a ixed arm 21 oii the machine frame. The feed 24,. and is preventedfroin moving longituf dinally thereon in one direction by a s eeve 23a which lis secured to the shaft 24 by a set screw,

' The shaft 24 has cone bearings at its ends vvwhich cooperate with anti-friction balls 24'* 1) which revolve in circular racene rac'eway is formed in a bracket 24b`th`at is Secured to the top plate 2 ofthe machinaamd the-other .raceway is formed in a screwathreadedadjustable plug 24 that takes: into a threaded opening in the bracket The ,vertical elongated slot 73 in each arm 2t" which forms part of the brackctplb. By these n'ieans an ellieient ball bearing supprovided for the shaft .2l andthe g ;-i may be.' turned by a screw driver, slot being provided in the plug for this purpose) to compensate for any .wearthat may take place in the balls or tl'iebcarings. The shaft 2l is connected to a feed pinion Qi) which meshes with a feed rack i3' that is carried by the carriage. The feed rack is mounted upon /ariiis 5'( that project from a ioclt shaft 5S to which is secured a leaIn spring 59 (see Fig. l), the free end of which bears against a portion of the carriage, as shown at (30,.in order Vto maintain the feed rack 4.2% nbrmally in engagement with its co operating feed pinion Q9. The rock lshaft 5 8 is likewise provided with a lug 6l which is bifurcatetl at Gi?, so as to provide steps 63 that cooperate -with a fixed pin 6l carried upon the carriage, in order to limit the oseillation ol' the rock shaft.

'l'he rock shaft 58 has a finger-piece or arm ta secured to one end thereof,` preferably the left hand end, so that a dej'iression this finger-piece or arm G5 will rock the shaft 58, thus disengaging the feed rack i3 from its pinion :29 to permit the carriage t0 he freely moved in either direction. v

ln the .ordinary Densnicre machine the paper carriage as an entirety comprises three oi inet members.

frame that ,carries the feed rack, and herefiniter these parts will generally be designated respet ivelv as the platen frame, the

pauci'i carriage and the feed carriage.

The feed carriage compr 'whit-1i the roel; shat't that extends substantially from cud to end of the frame,` is pivoted. 'lhe rear` portion of the feed car riage -lt frrooved longitudinally at Gl' to torni a traen ter cooperation with' horizontal hearing roller, (58 carried by the rear guide rail (al.

chine by headed screws 71 whichl throoo'h slots'. 72 in the bracket and enter .tappeti holes in the top plate. rlhis ar- I viz.; a frame carrying the' platen, a, carriage m which the platen traine as mounted or supported, and a trucli or bracketperinits a vertical'adjustment of the back guide rail (59 so that the rail not onlyhas a horiaoptal but a vertical adjustment as well, in orderl to properly position it and Aits bearing rollers with relation tothe track 6T in vthe feed carriage. Each of rollers 68 may be individually adjusted axially by the screw threaded adjustable bearing plugs GSK see Figs. Ll and 5, which are cup-like at their inner ends and contain anti-l`riction balls 158iL against which the coned hub or axle of cach roller bears.

Projecting forwardly from the feed carriage traine 6G are eyes 75 (Figs. lV and 2) that surround a tubular bearing sleeve 76, and which may be secured thereto by screws 7T. The sleeve T6 may be of any desired length but we prefer to extend it substan tially throughout the length of the carriage t'oi' purposes which will hereinafter more cle-arbv appear. This tubular bearing sleeve 7G surrounds an adjustable traverse rod 78 which is supported upon arms or standards T9 projecting up from the top plate and the rod is provided with two parallel longitudinal grooves which receive two sets of anti-friction rollers or balls 8l, 82. Y y

From an. examination ot Figi of the drawings, it will be observed thatl the series of balls 8l are arranged in a groove 80 on the top of the rod 78j whereas the series of balls 82 are arranged in a groove 80 on the rear side of the rod; and that the sleeve 76 bears against both series of balls. In order to prevent the feed carriage from lifting, we provide the sleeve 76 with pins Sfwhich normally are out of contact with the under side of traverse rod. lVhen, liowever,' a slight upward movement isgiven to thecarriage which-would tend-to displace it, the pins 83 on -the sleeve are brought into oontact with the traverse rod and prevent such displacement. In order that the loose and freely movable anti-friction balls 81 and S2 may not escape from the tubular sleeve, each end thereof is provided with a segmental flange 8l. l

Surrounding the sleeve 76 are xed roller bearing collars 8,5 (see Figs. 2 and 8) that are provided with lball bearing racewaysSG in which anti-friction rollers or balls 87 travel. The rollers 87 in each bearing cooperate with a beveled endSS of a revol'uble sleeve 89.*) ,Thdsleeve S9 has an internal diameteiwliieh is larger than the external diameter olI the tubular'sleeve 7G and sur-v rounds and is adapted to revolve around the sleeve' on the` ball bearings and without touching the'saine. "llie collars S5 nay be maintained' in thei' adjusted position upon l the beaiingsleeve 76 by set screws 90. The beveling vor tapering of each end of the sleeve 89 not only provides thrust bearings forlimiting the endwise movement of tlierl Mattei A sleeve with relation to its bearings but it likewise forms with the halls a hearing which takes the direct strainer pressure ap plied to the bearing sleeve 89. This sleeve is adapted to support an arm. 91 connected to the platen carriage and thus provide a hall hearing support for the transverse movement of the pla-ten carriage when it is.

shifted for upper and lower printing,

as will hereinafter more clearly appear.

The ends of the tubular sleeve 76 are cut away on the underside for a considerable of the length ot' the sleeve as is indicated iiiy Fig. 11 of the dra-wings. The purpose of cutting away the tubular sleeve in the manner described is to permit the sleeve to pass beyond the supports 79 for the traverse rod in the movement of the carriage from end to end ot the machine.. While the tubular .sleeve may he shortened in order to permit this movement, we prefer to employ a long sleeve and cnt away the lower portion of the sleeve in order to provide an elongated bearing surface for t e anti-friction' rollers 81 82 throughout a considerable lenofth of the" carriage so that there will be no liability of the carriage wahhling or rockin when at or near either extreme of its travel.

Referring particularly to Fig. 11 of the drawings, ity willhe seen'that the cutaway poi't-ionof the sleeve 7 0 terminates at '02 so that suhstantially the distance between the point and the corresponding -eiid of the sleeie may extend beyond the support T9 al either end of the machine.

ln order that the traverse rod 78 may be vertically adjusted to maintain an exact parallelism between said rod and the front and rear guide rods and so that no binding `ac- 'upper endV of the tion will take` place Vin the movement of the carriage. and the carriage will run true, we have provided adjusting means which are illustrated in Fig. 7 of the drawings. Said means comprise an adjustingl screw 93 which is provided with a hollow head that is iiiterna-lly screw-threaded and a depending screw steni 94. that. lis adapted to screw into a threaded openin in the support 79. The

' ollow head of this screw is seated within an aperture in the traverse rod 78 and hears against a. shoulder 95 formed therein. `Thus is will he seen tliat au elevation or lowering ot' the adjusting ,screw (and whicliniay he done with screw thljliead of the screw 96 hears against a suuflder 97 iii the traverse rod so as to innintain the rod clamped4 upon the adjusting screw. An inclosing cap 98 may he provided that partly surrounds the rod andl the cap and is scl'ewed'into the end of theI rod. ln order tf lireveiit ali accidental displacement of the adjusting screw, we may, in addition to the securing screw 90, provides hindiiio screw 100 which is adapted tosoicw into a lateral screw-threaded opening in the support 79 and to hear at its inner end upon the adjusting screw, thus locking the same in the adjusted position. stoodl that the adjusting means described is employed upon each end of the traverse rod so that an independent adjustment of each end thereof niay he el'ected. 1t will he seen that the employment of a cap prevents the admission of dustto the opening through which the adjusting screw is introduced.

The feed carriage 06 is provided with means for shifting the'plateii longitudinally with relation to said feed carriage for pur poses which will hereinafter appear. Thus, from an inspection of Fig. 2 oi' the drawings, it will he seen that a spindle 101 is seated to revolve in a bearing 102 that projects from the feed carriage and this spindle Itl will be undei'- justingl piece 100` consists of an elongated j har having slots or open-ings 108A and in these openings are-arranged Shanks ot thc headed-vertical screws 100 whichare secured in tapped holes in arms 77 that project forwardly from the frame 60 and ter'ininate in the eyes 77. Extending forwardly' from the adjusting piece 100 is an eye 110 that is internally sci'e\\'-thi'caded for thel rc:

caption of'an externallythreadednntloi' sleeve 111,.V which is preferably provided at itsy left-hand end with a square or octagona'l headr so that the sleeve may be'tu'rijied or manipulated by a thin bifurcated wrencl'i; a

foi-l; or yoke 11".)` projects rearwardly lfrom.

the platen vframe and hea-rs against .'tliefoi'iter side of said nut.

A'setscrew 113 passes through the 'eye'. 110

and bears upon the adjusting nutf1'11 to maintain it against accideiitaltnrning by the contacting yoke 112. yltwill 'heunderstood Ithat the nut'111 siii-'rounds the tubular sleeve TG and forms an additionalfconnection between it and thef feed carriage. 6641.50

`From an examination of Fig. 2 of the drawings, it will `be seen that the arm 114 and the nut 111 bear against the inner sides of their associated forks 115 =and 112. The nut 111 will take'up any lost motion due to wear between the platen carriage and the feed carriage and which would result in an y improper lateral alinement or spacing of the writing. In the present structure, if a slight independent longitudinal movement or lost motion exists between the platen carriage and the feed carriage, an adjustment of the i nut 111 to force it toward the fork 112, will take up such lost motion and theptrouble will be obviated. g

The purpose of the adjusting spindle 101 and its cooperating parts is to provide for a slight longitudinal movement of the platen,

so that corrections may be neatly made. It is sometimes necessary in -making corrections, to crowd a given number of letters within a space which previously contained fewer -letters in order to complete a .word and this it is not easy to do with the ordif nary'letter spacing mechanism; but with the aid of the mechanism which has just been correctposition to start the word.

described and by turning the spindle 101 the platen can be shifted a fraction of a letter space distance and the4 word completed in lthis manner. Assuming that live letters are to be written in the space formerly occupied by four, the carriage will be moved to the The spindle 103 may then be turned to adjust or feed the platen endwise so that the next impression will be brought closer to the last letter written than would be the case if the feed was produced bv thel regular letter spacing mechanism. This may give sutlidinary lettervspace feeding mechanism. It may, however, be necessary to feed the platen by the screw-spimlle 103 several times partial letter space distances to get all of the letters within. the prescribed space on the paper; and in some instances the letters will overlap.

When the knob of the pindle is turned in' thedirectionof the ar 'ow fat the knob in Figs. 1 and 2, the platen carriage and platen will be fed by the screw 104 and nut 105 toward the left and when the knob is turned the other way the platen carriage and platen will be fed toward the right. Vhen the spindle 101" is turned to the right, the ad-` justing piece' 106 will be moved in the `'direc- 133 of the bearing rollers 129.

tion of 'the arrow in Fig. 2 ofthe drawings, thus moving the entire platen carriage to 4the right, while the feed carriage remains relatively fixed. This movement of the platen carriage as a whole is produced bythe arm 114 forcing the fork 115t`o the right and with it the entire platen carriage. Whenv Athe spindle is turned in an opposite direction, the nut 111 will be carried with the ad. justing piece l106 to the left or in a direction opposite to that indicated by the arrow in ,Y F ig. 2 and the adjusting nut contacting with the fork 112 will produce a corresponding movement of the platen carriage.

The platen carriage referred to comprises a four-sided framemade up of end plates 116,-a rear bar 117, to which the forks 112, 115, are connected, and front connecting bars 118, 119.- The end plates 116 may be provided with slotted bearings 120, for. the

reception of a shaft 121 of the platen 122 and may likewise be slotted to provide a bearing surface for anti-friction rollers 124 that a-re carried by the platen frame 125 in substantially the same manner as in the well known Densmore machine.. The connecting bar 118 which unites the end plates is provided with a carriage scale 126 that coperates with a fixed pointer 127 secured to the shift rod or rail 120.

The bar 119, in addition to forming a connecting bar between the ends plates, may be grooved, as indicated at 128, to form a trackway for anti-friction rollers 129 that are carried by the shift rod 130. Thesebear-V ing rollers 129 are represented in detail in Figs. 3 and 4 of the drawings, from which .it will be seen that adjustable bearings 131l are -formed of externally screw-threaded. plugs which are adapted to take in Giarre'- sponding screw-threaded openings in the shift rod andthat each of these bearings is provided with a circular. raceway for the reception of anti-friction balls 132 which are adapted to support the coned bearings The bearl; ings 131 are each provided with a slit 134 cient room for the remaining letters, 111i which event the platen may be fed by the ori for the accommodation of a screwdriver, by means of which the bearings can be readily turned to adjust lthevrollers 129 individually with reference to the trackway 128 in the first instance and when wear takes place subsequently, and so that the y'carriage rail 119 shall at all times be properly supported. on and travel truly on said rollers 129. The means for supporting the bearingrollers 68 and 129 are the same. f

los

From an examination'of Figs. 2 and 10 lof the drawings, it. willrbe seen that shoulbearings -120 are formed to maintain the platen and its fr 1e movement with regi against longitudinal tion to the platen car-1130.

l the bearings 120 thereof.

a slight endwise shake or lost motion sometimes results therefrom -and the letters are in consequence unevenly spaced. ln order to overcome this `oltjection I have made one of the Shoulders 136 inthe form a screw threaded collar which is slotted at 137 sc that the collar may be adjusted'by a screw driver. This screw-threaded collar is screwed into an internally threaded boss 138 forming a portion of the platen frame.

By this means it will be seen that any lost motion which may be produced by Wear u ,on the parts may be readily taken up by a justing the screw -threaded collar out- 2Q, wardly to compensate for such wear.

The platenl frame may be provided lWith the usual fixed finger vpie'ce 139, by means of which the platen can be turned backto inspect the writing.

Reference being had particularly to Fig 1 and 2 0I" the drawings, it will be observed that the shift bar 130V4 is provided.. tvith depending arms 216 which are pivoted to the training of. the' machine There are two of structures embodying eitherv one or the other.

these depending arms 216 and a rock shaft 217 extends from side to side of the machine (see Fig. 2) and serves as pivots for vthe arms 216. Thedepending arm 216 at one side of the machine, preferably at the left-hand side, is extended to forni a depending projection or arm 218 which is operative y .connected to suitable temporary shift key levers 226 and 231, bearing finger keys 228 and 232 respectively and toa permanent shift key 235 by means of which the platen may be either temporarily or-perma- `nently shifted transversely from Vone case position to the other.

TWe have applied the term roller bearing and bearing roller to various parts described herein, though it should be understood that said terms are intended to apply to either anti-friction' rollers or balls and to Various changes' in detail construction may be made Without departing from the gist of our several improvements.

Certain features shown and describedare not claimed herein, butconstitute the subjects-matter ofseparate divisional 'applications, filed on the third day'of June, 1902, and bearing respectively, Serial Numbers 110,041, 110,042 and 110,043, and on -June .6,
